Compound amino acid injection and preparation technology process thereof

The invention belongs to the field of medical preparations, and in particular relates to a compound amino acid injection and a preparation technology process thereof. The compound amino acid injection provided by the invention comprises 17 amino acids, respectively beingnamely L-leucine, L-valine, L-isoleucine, L-phenylalanine, L-alanine, L-methionine, L-praline, L-glutamic acid, L-arginine, L-lysine, L-tyrosine, L-aspartate, L-tryptophane, L-serine, L-threonine, L-histidine and L-glycine, and further comprises cysteine. The compound amino acid injection provided by the invention solves the problem that in the prior art, the compound amino acid injection is subjected to oxidative degradation when in a high-temperature preparation and sterilization process. According to the preparation technology of the compound amino acid injection, the amino acid injection can completely get rid of the use of sulfite, preparation temperature in the preparation process is greatly reduced, and stability of the compound amino a
